The instruction booklet for your pressure cooker indicates that its highest setting is 11.4 psi. You know that standard atmospheric pressure is 14.7 psi, so the booklet must mean 11.4 psi above atmospheric pressure. At what temperature will your food cook in this pressure cooker set on "high"?
you have to look at what is the bp of water at 26.1 psi. http://www.engineeringtoolbox.com/boiling-point-water-d_926.html
Use the Clausius-Clapeyron equation
Rearrange it and plug in the numbers
dHvap= 40.68 kJ/mol= 40680 J/mol
R= 8.134 J/mol
T2= 100C= 373K
